Anyone have any experience getting a damaged TCM repaired? Any reputable companies that you have used for this? This TCM had a power wire arc against the aluminum heat sink - now no continuity (as checked between pins 9 and 69).

Hmm...maybe this is something my son can do for extra money?

take a wire to one of the heat syncs on the outside case, find a nut that screws on one. Tighten the wire down against it, then run the other end of the wire to battery ground. Iv had this fix a bunch of tcms that have been arched on.
